Maybe a card magician who travels through different wizarding schools in the Harry Potter universe using their card magic as a form of communication and as a tool to solve mysteries. For example, they could use cards to find hidden passages or secrets in Hogwarts, Beauxbatons, and Durmstrang. The cards might have special symbols that only the magician can understand and that are related to the history and magic of each school.
One idea could be a young wizard who discovers they have a unique talent for card magic within the wizarding world. They use their card tricks to outwit dark wizards, like making cards transform into protective spells or creatures to fend off attacks.
One idea could be a young wizard who discovers a rare deck of magic cards that have the power to transport him to different parts of the wizarding world. He could use these cards to solve mysteries and help his friends.
One idea could be creating a new type of card that has a special power related to time - like being able to go back in time during a game. Another could be a story where a character discovers a rare and powerful card that was thought to be lost forever. And a third idea might be a tournament where the cards have been enchanted in strange ways, causing unexpected things to happen during the matches.
One idea could be a wizard using card magic to solve a mystery at Hogwarts. Maybe the cards hold clues that only the protagonist can decipher through their knowledge of card magic.
Perhaps an older wizard who has been in the wizarding world for a long time but has always been on the outskirts because of his unique card magic. He decides to come to Hogwarts to teach the students about this different form of magic and ends up getting involved in all sorts of adventures with them. He could have a mysterious past and a connection to some of the darker elements in the wizarding world that he is trying to keep at bay with his card magic.
It could be a new student at Hogwarts who has a natural talent for card magic. Maybe they come from a family of muggle magicians and bring a unique perspective to the wizarding world of magic.
One idea could be a crossover where characters from both universes meet. For example, Harry Potter could encounter Eragon and they could learn from each other's magic systems. Maybe Harry could teach Eragon about some of the more complex spells in the wizarding world, while Eragon shows Harry how to bond with a dragon in a more in - depth way.
You could also create a plot where a character who thought they had no connection to the Potter heritage suddenly discovers they do. This revelation could change their entire life. They might have to deal with newfound magical abilities that come with the Potter bloodline, and also face the enemies that the Potter family has made over the years, like some die - hard Death Eaters who still hold grudges.
A great plot idea might be a Craftsmith who is actually a descendant of an ancient wizarding family with long - lost spells and abilities. This Craftsmith uses their skills to recreate those spells and in the process, uncovers a plot by dark wizards to use these forgotten magics for evil. As the story unfolds, the main characters have to stop the dark wizards while also learning about the new and old magics.
One idea could be exploring what would happen if a new, mysterious student joined Hogwarts during the Triwizard Tournament. This student could have a hidden agenda related to the Dark Arts and start influencing the events of the tournament in unexpected ways.
One idea could be that the orphanage is a hidden place for magical orphans with special powers. The orphans form a secret society within the orphanage to protect themselves from dark wizards who want to use their powers. They learn magic on their own, using old books they find in the attic of the orphanage.
